2014-02-10pci/shpc: convert SHPC hotplug to use hotplug-handler APIIgor Mammedov1-0/+8
Split shpc_device_hotplug() into hotplug/unplug callbacks and register them as "hotplug-handler" interface implementation of PCI_BRIDGE_DEV device.

2014-02-10qdev: add "hotpluggable" property to DeviceIgor Mammedov1-0/+3
Currently it's possible to make PCIDevice not hotpluggable by using no_hotplug field of PCIDeviceClass. However it limits this only to PCI devices and prevents from generalizing hotplug code. So add similar field to DeviceClass so it could be reused with other Devices and would allow to replace PCI specific hotplug callbacks with generic implementation. Following patches will replace PCIDeviceClass.no_hotplug with this new property. In addition expose field as "hotpluggable" readonly property, to make it possible to read its value via QOM interface. Make DeviceClass hotpluggable by default as it was assumed before. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

2014-02-10qdev: add to BusState "hotplug-handler" linkIgor Mammedov1-0/+12
It will allow to reuse field with different BUSes, reducing code duplication. Field is intended for replacing 'hotplug_qdev' field in PCIBus and also will allow to avoid adding equivalent field to DimmBus with possiblitity to refactor other BUSes to use it instead of custom field. In addition once all users of allow_hotplug field are converted to new API, link could replace allow_hotplug field in qdev hotplug code.

Right now the arm gic emulation doesn't keep track of the source of an SGI (which apparently Linux guests don't use, or they're fine with assuming CPU 0 always). Add the necessary matrix on the GICState structure and maintain the data when setting and clearing the pending state of an IRQ and make the state visible to the guest.

This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times.

PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Design - each bus gets assigned "bsel" property. - ACPI code writes this number to a new BNUM register, then uses existing UP/DOWN registers to probe slot status; to eject, write number to BNUM register, then slot into existing EJ. The interface is actually backwards-compatible with existing PIIX4 ACPI (though not migration compatible). This is split out from PIIX4 codebase so we can reuse it for Q35 as well.

2013-12-23piix: fix 32bit pci holeGerd Hoffmann1-0/+1
Make the 32bit pci hole start at end of ram, so all possible address space is covered. We used to try and make addresses aligned so they are easier to cover with MTRRs, but since they are cosmetic on KVM, this is probably not worth worrying about. Of course the firmware can use less than that. Leaving space unused is no problem, mapping pci bars outside the hole causes problems though.

2013-12-23qdev: switch reset to post-orderPaolo Bonzini1-1/+1
Post-order is the only sensible direction for the reset signals. For example, suppose pre-order is used and the parent has some data structures that cache children state (for example a list of active requests). When the reset method is invoked on the parent, these caches could be in any state. If post-order is used, on the other hand, these will be in a known state when the reset method is invoked on the parent. This change means that it is no longer possible to block the visit of the devices, so the callback is changed to return void. This is not a problem, because PCI was returning 1 exactly in order to achieve the same ordering that this patch implements. PCI can then rely on the qdev core having sent a "reset signal" (whatever that means) to the device, and only do the PCI-specific initialization with pci_do_device_reset.
